.SH DESCRIPTION
The byte string functions perform operations on strings (byte arrays)
that are not necessarily null-terminated.
See the individual man pages
for descriptions of each function.
.SH NOTES
The functions
.BR bcmp (),
.BR bcopy (),
and
.BR bzero ()
are obsolete.
Use
.BR memcmp (),
.BR memcpy (),
and
.BR memset ()
instead.
.\" The old functions are not even available on some non-GNU/Linux systems.
